Bug in Lazarus package in Debian

[Petr Hlozek <petr@ok2cqr.com>]

Hello Abou,

current Lazarus version in Debian Unstable will not compile any app.
The compilation ends with this error:
PPU Loading /usr/lib/lazarus/0.9.30.2/lcl/units/x86_64-linux/gtk2/interfaces.ppu
PPU Invalid Version 104
Fatal: Can't find unit Interface

Lazarus in Precise Pangolin works without any problem. The only
difference we found is the fpc-compiler version. If you rebuild
Lazarus with fpc-compiler version in Debian unstable, we think it will
work again.
I would like to ask you if you could also apply a patch I'm sending.
It fixes bug in Lazarus which is on systems with glib version >= 2.31
where Lazarus itself and also all apps builded in it freeze after
start. The author is Zeljan Rikalo and bug is reported here:
http://bugs.freepascal.org/view.php?id=21129

If you want to test if the rebuild helped, you can try to rebuild
cqrlog package. The cqrlog package in Debian did build fine with the
fp-compiler 2.4 versions but fails with your recently uploaded
fp-compiler 2.6.0-1

Thanks a lot!

Petr
